Python Matplotlib.axes.Axes.get_lines()用法及代碼示例

Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。軸類包含大多數圖形元素:Axis,Tick,Line2D,Text,Polygon等,並設置坐標係。 Axes實例通過callbacks屬性支持回調。

matplotlib.axes.Axes.get_lines()函數

matplotlib庫的axiss模塊中的Axes.get_lines()函數用於返回Axes包含的線的列表

用法: Axes.get_lines(self)


參數:此方法不接受任何參數。

返回:此方法返回軸包含的行的列表。

以下示例說明了matplotlib.axes中的matplotlib.axes.Axes.get_lines()函數:

範例1:

# Implementation of matplotlib function 
from matplotlib import colors 
from matplotlib.ticker import PercentFormatter 
import numpy as np 
import matplotlib.pyplot as plt 
  
  
N_points = 100000
x = np.random.randn(N_points) 
y = .4 * x + np.random.randn(100000) + 5
   
fig, ax = plt.subplots() 
ax.hist2d(x, y, bins = 100, 
          norm = colors.LogNorm(),  
          cmap ="Greens") 
  
w = list(ax.get_lines()) 
if len(w)== 0:
    ax.text(-2, 8.5,  
            "No line contained by the Axes \n") 
else:
    ax.text(-3, 8.5, 
            "List of the lines contained by the Axes \n") 
    x = 8.5
    for i in w:
          
        ax.text(-3, x-0.5, str(i)) 
        x-= 0.5
  
fig.suptitle('matplotlib.axes.Axes.get_lines() \ 
function Example', fontweight ="bold") 
  
plt.show()

輸出:

範例2:

# Implementation of matplotlib function 
import numpy as np 
import matplotlib.pyplot as plt 
import matplotlib.patches as mpatches 
  
  
fig, ax = plt.subplots() 
x, y = 10 * np.random.rand(2, 1000) 
ax.plot(x, y, 'go', alpha = 0.2) 
  
circ = mpatches.Circle((0.5, 0.5), 
                       0.25, 
                       transform = ax.transAxes, 
                       facecolor ='blue', 
                       alpha = 0.75) 
  
ax.add_patch(circ) 
  
w = list(ax.get_lines()) 
  
if len(w)== 0:
    ax.text(1, 8.5, 
            "No line contained by the Axes \n") 
      
else:
    ax.text(1, 8.5, 
            "List of the lines contained by the Axes \n") 
    x = 8.5
      
    for i in w:
        ax.text(1, x-0.5, str(i)) 
        x-= 0.5
  
fig.suptitle('matplotlib.axes.Axes.get_lines() \ 
function Example', fontweight ="bold") 
  
plt.show()

輸出:
